domain name system - Windows AD with external DNS

How do I configure Windows AD to use an external DNS server? We have a tool for managing DNS. We're attempting to use Windows AD for authentication. In order to get a server to join the domain, we must point it to the AD server as DNS. However, in so doing, the server that is pointed to the AD server for DNS can no longer resolve hostnames in our environment.

We're using example.com for our login domain across the environment. All of our servers are servername.subdomain.example.com.

When I join servername1.subdomain.example.com to the domain it can no longer resolve servername2.subdomain.example.com, unless I manually add the DNS entry for servername2.subdomain.example.com do the DNS on the AD server.

We don't want to have to create two DNS entries for everything so we need the AD server to look at the external DNS server for DNS.

I attempted to create a Forward Lookup Stub zone for subdomain.example.com but when I get to the "Specify the DNS servers from which you want to load the zone" and enter my dns server I get an error when attempting to validate: "An unknown error occurred"

Attempting to add a new delegation under my existing example.com domain is bet with the same error when adding DNS servers.

Admittedly, I'm not a Windows Admin and my understanding of AD is superficial at best, but it seems like what I'm asking for should be relatively simple... I'm just looking for a recursive lookup on hostnames from the domain controller.

Any pointers in the right direction are greatly appreciated.

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

ubuntu - Monitoring CPU, Mem, disk, on a single server

I've been looking for a simple starter solution for monitoring my [currently] single server hosted solution. Other than Nagios and similar, are there other good (simple) solutions people are using? Answer Everything depends on what you want. For example Munin is very simple, you can install and configure it in less then 10 minutes (on one server), it can sends alarms, make graphs from monitoring cpu, mem. apache connections, eaccellerator, disk io and many many more (it has many plugins). But if you are planning in future get some more machines, munin may not be enough. For example in munin you cant monitor state of individual processes, can't monitor changes in files (for security purpose). So if you wanna only see what is the utilization of basics parameters on your server and don't plan to buy some more servers Munin is what you are looking for, but if you wanna be alarmed when some of your service is down, take more control on what is happeninig on...

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits, ...
